Recently the study of one loop Witten diagrams has been considered from the dual perspective by computing the \(1/N\)  expansion of scalar correlators in conformal field theories with holographic description by means of the analityc bootstrap. More concretely, in [1]} a method was developed to solve the crossing equations as an expansion in large spin. The given expansion can be resumed and then extrapolated to lower spin (see also [2]}, [3]}). This approach has been used in [4]}, [5]}, [6]} to compute some one loop corrections to the four-point function of conformal fields with low conformal dimension, specifically \(\Delta =2\)  (for related recent work see also [7]}, [8]}). It is our hope that we can reproduce those result in the near future by improving the approach initiated in this note.
